Dot pitch

This is the distance between two dots of the same colour. This is generally measured diagonally, but for aperture grille monitors it is sometimes measured horizontally.

Pixel response time (rise+fall)

Pixel response time is as important when choosing a LCD monitor what refresh rate is for CRTs. The response time is the time, which a TFT cell requires to switch on and switch off. For standard office applications a response time of 70 ms (milliseconds) is sufficient, but for multimedia values under 30 ms are required.

Contrast

Contrast is measured as the ratio between the light intensity of the brightest and the darkest point of an image. High contrast values improve readability and ergonomics.

Brightness

Brightness is the emitted luminous power over a specified area. Brightness is another point, on which LCD monitors are superior to CRT devices. Traditional monitors create approximately 80 to 100 cd/m² (candela per meter square). For LCDs, values below 200 cm/m² are not acceptable.

250 nit (cd/m2)

Horizontal viewing angle

The viewing angle is the angle from the centre of the image where you can still see the image. Ergonomic requirements are at least 120 degrees horizontally.

178 degrees

Vertical viewing angle

The viewing angle is the angle from the centre of the image where you can still see the image. Ergonomic requirements are at least 90 degrees vertically.

178 degrees

Horizontal frequency

The speed that a monitor draws a single scan line, called the "horizontal frequency," is measured in kilohertz (kHz). The process repeats, painting line after line, until the screen is filled.

30~83 kHz

Vertical frequency

The speed that a monitor draws an entire screen, called the "vertical refresh rate" or "frequency," is measured in hertz (Hz).
